VALVE-CHAMBER FOR WATER-COLUMNS.

Specification of Letters Patent.

Application filed August 21, 1908.

Patented May 10, 1910. Serial No. 513,906.

To all whom it may concern:

Be it known that I, F RANK 0. ANDERSON, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Valve-Chambers for VVater-Oolumns, of which the following is a specification.

My invention relates to improvements in valve chambers for water columns, and more particularly to that type of valve chamber which engages the pipe of the water column.

It is the object of my invention to provide means whereby easy access may be made to certain parts of' the valve chamber without raising the water column.

Another object of my invention is to provide an extension on the pipe of the water column at its lower end which is considerably weaker than the valve chamber and the pipe of the water column. In the present method the pipe of the water column engages the valve chamber direct and when the water column is knocked down it naturally tends to break the valve chamber. It is seen that the casting forming the valve chamber is a very expensive one and cannot be replaced without considerable cost. In my improvement when the water column is knocked down by accident or carelessness of the operator the extension which I have provided being weaker than the valve chamber and the water column pipe is broken without any damage to the valve chamber or pipe. On account of the water spout extending horizontally from the top of the water column, the water column is made slightly top heavy and as its lower end requires packing, said packing is not equally worn by the turning of the column because of the fact that said column has been made top heavy.

A still further object of my invention is to provide means whereby the packing of the pipe of the Water column receives an even wear.

My invention also consists in certain new and novel parts and combination of parts as will hereinafter be described and pointed out in the appended claims.

Referring to the drawing: Figure 1 is a vertical section taken through a valve chamber and a portion of a water column equipped with my invention. Fig. 2 is a perspective view of one of the principal elements of my invention. Fig. 3 is a cross section taken on the line 3-3 of Fig. 1.

Referring more particularly to the drawing, 10 indicates a water column of the usual design, 11 shows the customary mounting of same and 12 shows a support for the mounting 11. The main valve chamber is shown at 13, and 14 shows the customary valve stem for operating said valve. At 15 I show the main valve having a stem 16 and a waste valve 17 all mounted in the customary manner. The valve seat 18 is also mounted in the customary manner. At 19 I show a separable extension, the parts of which are adapted to be bolted together through bolt holes 20. The separable extension is more clearly shown in Fig. 2 and is provided with flanges 21 in which the bolt holes 20 are located. A support 22 is provided on the inner side of the extension 19 to form a support for the column when it is being erected.

The packing 28 for the pipe of the water column is clamped down by a packing ring 24, said packing ring having mounted thereon roller 25 to form a bearing for the pipe of the water column. Thus it is seen that when the pipe of the water column is turned it will bear against the rollers 25 instead of bearing unevenly against the packing 24; as it now does in the present style of valve chamber. Of course, the rollers are firmly mounted and there may be as many as desired, four being shown. At 26 I show the customary bridge placed in the pipe of the water column and through which the operating stem 14 operates.

The advantage of constructing a valve chamber after this method may be readily seen when the operation of the device is explained. For instance, if it becomes necessary for a workman to repair or examine any of the mechanism inside of the valve chamber, it is not necessary for him to raise the column but simply to raise the packing ring 24, fasten it at any desired height on the water column and then unbolt the extension 19 and open up the valve chamber at the top. In this way it is apparent that he has easy access to the bridge 26 placed in the pipe in the water column and to the bushing 27 and to all the mechanism inside of the valve chamber, which he cannot get access to by removing the plate 28 which has the valve seat mounted thereon. This improvement entirely dispenses with the hand hole plates now commonly used to gain access to the valve chamber. It is also apparent that by means of the rollers 25 that the packing 23 will wear more evenly due to the fact that the rollers 25 form a bearing for the pipe or water column 10. Furthermore, if the water column should happen to be knocked down through carelessness of the operator, the extension 19 being weaker than the casing of the main valve chamber 13 and also weaker than the water column 10 would be the first to break thereby eliminating the danger of fracturing the main valve casing. The extension 19 is placed in a position where it is easily mounted or removed as desired.

My invention may be modified in various ways without departing from its spirit and scope, and I do not wish to be confined to the exact details shown.

What I claim as new and desire to secure by Letters Patent is:

1. A valve chamber for water columns having an extension mounted thereon, said extension being made in halves adapted to be bolted together, a packing ring mounted on the said extension and friction rollers mounted on said packing ring, substantially as and for the purposes set forth.

2. A device of the character described comprising a water column, a valve chamber formed of one casting, an extension placed between said valve chamber and said water column and mounted on said valve chamber, said extension being made in separable parts and bolted together and to be removed separately without moving or disturbing any part of the valve chamber or water column or the mechanism of either, substantially as and for the purposes set forth.

3. In a device of the character described, a water column, a valve chamber, a packing for said water column, a packing ring, and friction rollers mounted upon said ring and bearing against said water column, substantially as and for the purposes set forth.

4:. A device of the character described comprising a water column, a valve chamber, an extension made in parts, said parts adapted to be bolted together mounted upon said,

valve chamber, packing placed between said water column and said parts, a packing ring fastened to said parts, and friction rollers mounted on said packing ring and bearing against the water column, substantially as and for the purposes set forth.

5. In a device of the character described, a water column, a valve chamber, and an extension made weaker than said water 001- umn and valve chamber, respectively, and interposed between said water column and valve chamber, substantially as and for the purposes set forth.
